JB3 Uninstall Help

Syndicategt · 11-06-2009, 10:08 PM

So I have a HPFP issue and need to take her in to the dealer tomorrow. I just took out my JB3 and set the ECU back to stock (I followed all the directions carefully). When I go to start the car up it will not crank, it basically stays in the "start mode" trying to crank the engine. There was also a noise from the ECU. All the plugs are in firmly and so are the brackets. Any ideas?

Something is not connected right. Check it again. Infact, try reinstalling and I bet you will find where you messed up.

Phew got it working. I reinstalled it and it's working fine, everything seemed to be connected the first time. Hope I get a new HPFP and spark plugs tomorow

. Engine is running fine now.

Edit. I think my old eyes confused the grey and white sub connectors

You didnt get a check engine did you? Just wondering if you threw any codes trying to start the car with the incorrect harness connected...

Make sure you clear everything with a BT tool. Then restart the car. The hpfp codes will come back but all the tune codes and ecu mangling codes you created will go away.
